Abstract

In an electrical plug (1) having a plug housing (2) consisting of plastic and having at least one plastic-injection-moulded metal insert part (3, 4), which is provided therein and is exposed on at least one housing side (2a, 2b), according to the invention the plug housing (2) and the metal insert part (3, 4) are sealed off from one another by a cured sealing compound or adhesive compound (6), which is provided on the at least one housing side (2a, 2b) annularly around the exposed metal insert part (3, 4).

Description

Plug with metal insert of sealing
Technical field
The present invention relates to a kind of plug that connects by claim 1 electric plug as described in the preamble.
Background technology
Making plug with plastics extruding encapsulated metal insert is widespread.At this, plug is a problem at metal to the sealing on the interface of plastics, because the material fit between plastics and the metal connects because the right very different thermal coefficient of expansion of material is non-constant.However, in order to obtain the sealing of plug, the often measure that need expend, the seal that for example pre-extruding is sealed or added.
Summary of the invention
Has such advantage with it relatively by the plug with characteristic features of claim 1 of the present invention, promptly with the reliably and effectively connection of the key between the plastics sealed of sealing metal insert and extruding of simple method.By the present invention, then standard procedure " is pushed the encapsulated metal insert with plastics ", by the sealing on fluid sealant or the binding agent realization plastic/metal interface.The gel that fluid sealant or binding agent are preferably age-hardenable, especially PFPE (Perfluorpolyether) gel (Shin-Etsu of the Shin-Etsu Chemical Co., Ltd of Tokyo for example
Figure A200780006077D00031
8070, composition A and B) or silica gel (the Wacker-Chemie company of Burghausen for example
Figure A200780006077D00032
9242), or adhesive, the especially silica gel stick (DOW of the Dow Corning Co., Ltd of Wiesbaden for example
Figure A200780006077D00033
866 binding agents).Gel is the standard method that obtains proving, the salient point of this method is small cost and shirtsleeve operation.This has guaranteed and good being connected of the plastics and the metal of insert that wherein this connection also provides under high oscillating load.
For example can be by plug of the present invention as the electrical lead in the oil zone of automobile engine, especially as from having the electrical lead that come out in the inner space of the no oil of the high pressure sensor of surrounding environment influence sensitive electronic devices, be used for oily zone is sealed.This plug preferably detects the part of the pressure sensor of pressure accumulating tube pressure, and the electric lead of this pressure sensor is by outwards drawing by plug of the present invention.
Other advantage of theme of the present invention and favourable design can obtain from specification, accompanying drawing and claims.
Description of drawings
Shown in the drawings and explain in detail in the following description by the embodiment of plug of the present invention.Wherein:
Fig. 1 is the plug that has the mounting flange of sealing by of the present invention;
Fig. 2 is the plug that has the electrical contact of sealing by of the present invention;
Fig. 3 is the pressure sensor that has by plug of the present invention, and wherein electrical contact and mounting flange seal.
Embodiment
The plug shown in Figure 11 that electric plug connects comprise the plug casing 2 that is made of plastics and with the plastics extruding be encapsulated in this plug casing 2 the metal insert promptly three electrical contacts (pin) 3 and around mounting flange 4.The mounting flange 4 of annular or shell-like is the deep-draw part, and the end 4a that seals with the plastics extruding of this deep-draw part inwardly bends, and its outwardly directed flange end 4b has determined inner space 5.Electrical contact 3 is entering in the plug casing 2 on the case side 2a of inner space 5 and is coming out and enter inner space 5 from plug casing 2 on the case side 2b in face inside space 5.
Plug 1 is made of plastics with injection moulding process, and has as the contact 3 of metal insert and mounting flange 4 ground making and cool off subsequently.Yet, because the very different thermal coefficient of expansion of plastics and metal, connection between plug casing 2 and the metal insert 3,4 is packing less, thereby for example water can arrive in the inner space 5 in the slit between the mounting flange 4 along plug casing 2 and electrical contact 3 from the outside in other words.
However, in order to obtain the sealing of plug 1, plug casing 2 and the mounting flange 4 sealed with plastics extruding seal mutually by the fluid sealant or the binding agent 6 of age-hardening in Fig. 1, sealing glue or binding agent are applied to around mounting flange 4 on the case side 2b in face inside space 5 at the inner space gusset, just are applied on the plastic/metal interface of exposed inboard.Although do not illustrate, self-evidently also fluid sealant or binding agent 6 can be applied on the plastic/metal interface in the exposed outside around mounting flange 4 outer peripheral in inner space 5.
Different with Fig. 1, in the plug shown in Fig. 21, described plug casing 2 and the electrical contact 3 sealed with plastics extruding seal mutually by the fluid sealant or the binding agent 6 of age-hardening, and sealing glue or binding agent correspondingly center on contact 3 and be applied on the case side 2a of inner space 5.Although do not illustrate, the sealing of the self-evident inner space side that also can realize contact 3 and the dual-seal of contact 3 are just in two case side 2a, the dual-seal of carrying out on the 2b.
The fluid sealant of age-hardening or binding agent 6 be liquid seal and make by gel or bonding, method be with fluid sealant plastic and age-hardenable or binding agent around contact 3 in other words around mounting flange 4 be coated onto corresponding case side 2a in other words 2b go up and carry out age-hardening.By measure suitable when preparation, processed and the age-hardening, realize the fluid sealant of age-hardening or the no bubble (Blasenfreiheit) of binding agent 6.As shown in the figure, case side 2a, 2b only point-like ground at metal insert 3, cover with fluid sealant or binding agent 6 in 4 the zone, replace this scheme, case side 2a, 2b can certainly be in large area or gross area ground cover with preferred bed thickness uniformly with fluid sealant or binding agent 6.
Fig. 3 shows has the as above pressure accumulating tube pressure sensor 10 of the plug 1 of structure.This pressure accumulating tube pressure sensor 10 is with the opening in the nipple 11 sealing fuel accumulators (rail altogether), and wherein hex nut 12 is used to be screwed into.Plug 1 is fixed on this hex nut 12 hermetically with its mounting flange 4, for example is welded on this hex nut 12.Settled the pressure receiver (not shown) in inner space 5, this pressure receiver is connected on the fuel accumulator by the measurement lead 13 of nipple 11.Thus, plug 1 is as the lead-in wire of the liquid seal of the electric lead of drawing from the inner space that prevents surrounding environment influence 5 of pressure accumulating tube pressure sensor 10 of pressure receiver.In the plug shown in Fig. 31, electrical contact 3 as shown in Figure 2 and mounting flange as shown in Figure 14 are by fluid sealant or binding agent 6 sealings.
